A case of retrocaval ureter with a periureteric venous ring was reported. A 24 year-old man visited our clinic with asymptomatic gross hematuria. DIP and RP revealed right hydronephrosis and small “S” deformity of the right ureter. In surgery, it was found that the right ureter passed through the periureteric venous ring (type AB). Excision of the ventral vena cava and intubated ureterotomy were performed. The post operative course was uneventful and satisfactroy result was obtained. Prior to our report, only 4 cases of type AB had been mentioned by Rotter (1935), LePage (1972), Matsumura (1972) and Irikura (1973). Anomaly of post renal vena cava, especially type AB, was reviewed.
